If you want a different feel, the bit you need to focus on is the lever ratio not the bore of the master cylinder.

Yeah, you won't get any, intrinsic gain, from the brake lines. The stock lines are braided, or solid metal.

T5 (right hander after the long slow left?Or, the long slow left, off camber) at Portimao, isn't an especially hard braking corner. The stock ABS, is pretty amazing, you 100% won't feel anything at the lever, more, a kind of feeling, that the bike's not quite doing what you're asking, from the brakes. If (pretty sure you did) you had this feeling, that's the ABS, and bypassing it will be your friend.
Brake lines from Reactiveparts.com, and a couple of bolts in the ABS unit.

Although, word on the street, JetPrime MAY have an ABS delete dongle on the way....

it’s my understanding the ratio of caliper piston area to mc bore area significantly impacts lever feel (hard, short throw that’s more difficult to modulate vs a softer, long throw that’s easier to modulate).

Yes, the weird camber left hander which has a slightly downhill approach. It did feel very strange, no pulsing through the lever or anything though.

Yes because of the ratio being wrong .. eg putting a 19 on a panigale with std callipers! there is a sweet spot to hit in numbers for the perfect working ratio of Mc to calliper loads of this info on the inter web

Im referring to the lever ratio that can impact on lever feel ..

Just, didn't feel like the bike would slow as you would expect? But, still left you in control? It's an outrageously good system, but I don't think it's fully calibrated for a slick tyre in (almost) perfect conditions. Why you need to bypass it, when you get to that point.
I found, it really had a negative effect on my confidence, into the Melbourne Loop at Donington. Off camber, downhill, hard braking. Ring any bells! Everywhere else, it was epic. But when it took away that control, in those circumstances, it really knocked my braking confidence.
Bypassed it, and my braking control, and confidence, really improved. And, the braking setup, as stock, is unbelievably good

Even with the marketing angle, he's still way faster than me.

The thought occurred to me:

“A bike with a power:weight ratio of 1:1 (~200hp at 200kg) running steel brakes and a production tire, laps within a few seconds of a bike with a power:weight ratio nearly 100% higher (~300hp at 150kg) running carbon brakes, on a MotoGP spec tire? And we think that’s a credible report? Maybe if we’re talking a 30 or 40 second lap.”

And then I looked at the lap times for Valencia.

A “few” (3-4) seconds at Valencia is a huge difference. That equates to a 9-12 second gap at COTA. The panigale would be lapped twice in a typical race.

Marketing doing what it does.
